***New preprint from the lab*** showing “Generative replay across hippocampal-neocortical circuits”. In sleep we show spiking sequences in V1 (sensory neocortex!) that represent information that has not been directly experienced www.biorxiv.org/content/10.6... @bndu.ox.ac.uk @ndcnoxford.bsky.social

Generative replay across hippocampal-neocortical circuits

To make flexible decisions, the brain needs to make inferences between events that were not directly experienced together. In sharp-wave ripple (SWR) events, during periods of rest and sleep, spiking ...

Our paper is out today!!! (not an April fool's day joke) Congrats to authors @azulsilva.bsky.social, @belalima-paiva.bsky.social, Ele Pronier, and mostly to the amazing scientist and human being who led this project @facuumm.bsky.social #neuroskyence #hippocampus www.nature.com/articles/s41...

Dorsoventral hippocampus neural assemblies reactivate during sleep following an aversive experience - Nature Neuroscience

Synchronization of sharp-wave ripples across the dorsoventral hippocampus during sleep supports coordinated reactivation that represents negative experiences more faithfully than positive ones.

I’m building a foundational reading list for our lab (systems & circuit neuroscience, compneuro, modeling, neuromodulators, population coding etc.). I’d like to crowdsource recommendations. Which review(s) would you consider mandatory reading for the next generation of researchers?

Cell assemblies are drawing increasing attention in neuroscience, but one could argue that they are just an epiphenomenon. Is the activity of cell assemblies relevant for the brain? The short answer is yes. The long answer is in our paper, now online at PLOS Biology. 🧵👇 1/10 doi.org/10.1371/jour...

Adaptive communication between cell assemblies and “reader” neurons shapes flexible brain dynamics

Cell assemblies have been proposed as key units of brain activity, underlying diverse functions, but their basic features are not well understood. This study shows that interactions between cell assem...

1) This is a great idea. 2) I would be happy to mentor a project like this. If you want to do a project eg at the intersection of Philosophy of Science and NeuroAI, please feel free to reach out to discuss, or just put my name as a suggested mentor!

🗣️ With the support of the @danafoundation.bsky.social, we are very excited to announce the Philosophy & Neuroscience Collaborative Mentorship Program! 🧠 For more details & submission requirements, visit: philandneuro.com/mentorship (This is 1/2 announcements we will make over the next 1-2 weeks.)

Interested in doing a PhD on how #psychedelics (or other psychoactive substances) impact psychological or social processes @durhampsych.bsky.social ? Have a look at the NINE DTP scheme, now open. DM me if interested.

Thrilled to announce I'll be joining the Division of Neuroscience at @manchester.ac.uk as a Lecturer in Feb '26! The DuLab will explore how the brain integrates sensory streams into internal maps 🌐 using the rodent head-direction circuit, the 'neural compass', as a starting point for the journey 🧭

Spread the word! 🗣️🎙️ Together with @azulsilva.bsky.social and Bluesky-less Magdalena Miranda, supported by @elife.bsky.social, we’re organizing a webinar bringing together people working in science communication and outreach. Please, feel free to share the flyer with anyone who might be interested!

This is beautiful work and quite the discovery. This also plays nicely with the idea that superficial place cells are rigid and deep are flexible. Seems to suggest that the flexibility is more about past rep's integrating with newer rep's, than the opposite.

The naturalist Jane Goodall died today at 91. Hope, she argued, is not merely “passive wishful thinking” but a “crucial survival trait.” Revisit a conversation with Goodall, from 2021: nyer.cm/F55JtsS

I’m pleased to share our new paper, “Hippocampal ripple diversity organizes neuronal reactivation dynamics in the offline brain”, out in @cp-neuron.bsky.social ! With @vitorlds.bsky.social and David Dupret, we show that diversity in ripple current profiles shapes reactivation dynamics

The Sosa Lab website is now live! www.sosaneurolab.com We will be seeking a postdoctoral researcher to join the growing team! If you are a rodent neuroscientist and interested in doing systems neuro work in the mountains 🏔️, please check out the "Join" page.

I know it’s popular to think of citations as attribution of credit, but a part of me also likes to think of them as a trail of fun breadcrumbs for someone 20 years in the future.

Does publishing serve science or is science serving publishing? Damian Pattinson and I (@elife.bsky.social) argue scientific publishing has evolved into a system that, rather than facilitate scholarly communication, distorts and dictates it. onlinelibrary.wiley.com/doi/10.1002/... #OpenScience
